Having trouble with updating mods

I have never felt the need to update my mods except for now because I have an external PAID mod that is the crashhard dummy 2.0, and when I go to the link where I paid I cannot download it again for the update. Please help me!!!

NOTE: I no longer have the e-mail sent to me after purchasing the mod.

 

If you purchased it from Gumroad, go on the mod page, make sure you're logged in to your Gumroad account, and next to "Purchase again" you'll find a button named "View content", then download the lastest version.
If you purchased it from Ko-Fi, sorry I don't know how it works there.
If you have lost the account, either you repurchase it, either I can recommend you the AgentY's one which is free and supports more vehicles. It hasn't been updated for a year now, but you'll be sure it will update by itself one day.
